Used book - Veto Power, Léo Lapointe

Is the murder of a veterinarian in the early morning in a pasture on the Picardy coast the work of a prowler, as the Public Prosecutor's Office believes? Gendarme Paul Beauvillian accepts the official version but doesn't believe it. But when it's discovered that several veterinarians have died under strange circumstances all over France, the case takes a different turn. Clearly, someone is settling scores with a former class of students from the Toulouse veterinary school. Deep in the Picardy countryside, Gendarme Beauvillain follows the investigation with interest.
